Subject: [amibroker] Using Foreign with SAR, Short & Cover
> T_Close = Foreign(T, Close);
> Short = Cross(SAR(T_Close, 0.005, 0.05), T_Close);
> Cover = Cross(T_Close, SAR(T_Close, 0.005, 0.05));
>
> What is wrong with the above code for backtesting, please? Yes, I realize

> how do I tell SAR that I want it to exit from the current stock when a
> _different_ stock crosses the different stock's SAR?
>
> And why am I getting error msgs from the compiler about "T" being
> "uninitialized"? How do I explain to the compiler that I wish to refer to
> the "foreign" ticker symbol "T"?
>
> Finally, what is wrong with my use of "Short" and "Cover"? I can't get the
> compiler to accept this usage at all.
